To all whom it mag/concern: v l

Be it known that I, FRANZ WELS, ofNo. 31 Schoenbur 'strasse, Vienna, IV, Austria, a citizen of the Republic of Austria, have invented some new and useful Improvements in and Relating to a Power-Transmission Mechanism, of which the following is a specification.

he present invention, which has originated from exhaustive studies of the kinematic deflection of a fishs tail, cbnsists of the mechanical solution of the problem and its technical application "as an active ,propulsion or hydrodynamic driving mechanism, or also as a stationary active machine in any desired medium, whether .it be solid, semi-solid, gaseous, or liquid, or of an atmospheric or energetic character.

The local movement of the fishes, is effected by the vertebral mechanism, which,

' comparable with a running capsule mechations and R the resultant movement 'to the n'i's'm by diagonally produced muscular contractions, causes bending of the body 1) and which, alwa s commencing at the head, are directed backwardly anc, before they entirely cease with the unequal caudal fin, again recommence at the front. If two or more such impulses simultaneously flow through the vertebral column, then the result is the sinuous diagram according to Figure 1, in which c, c, c" indicate the thrust trajectories, the arrows their direcfront.

In a similar manner the oblique position of the broad sides takes place in the case of the segmen'ta lly moved wings of birds,

the inceptive point eof which in the same sinuous scheme V now lies u-p'on the line AB and the extreme sweep nt, n, of which represent the wave crest and wave trough; the difference between the wing and the fish-tail consistssolely in the fact that the former is only influenced on one side.

From the point ofview of research, fish and bird belong together and the latter has evolved from the former, passing through the reptile family, hencealso the relationship Serial No. 519,539.

upon the wave (Figure 1), the archetype oi thean'o'rganic world, the temporary abb of whlch is the graphic expression of all these movements.

Exhaustive, systematic experiments to design a mechanical movement of equal value have resulted in the arrangement shown in the accompanying drawings in which:

Figure l is a diagrammatic illustration of the movement of a fish.

Fig.2 is a .plan or lateral elevation of one embodiment offthe present invention, the dotand dash lines indicating the difierent positions successively assumed by the drivmg element V, while there is also illustrated diagrammatically .a plurality of such elements.

gig. 3 is a side elevation of the apparatus, an

Fig. 4 is a similar view in the direction G-E Fig. 2.; the same being shown partly insection.

Referring now, more particularly, to the accompanying drawings, there is provided a guide Z in which is journaled a shaft carrying the crank or eccentric K, the outer end of which is 'pivotally connected with a connecting rod P. The opposite end of this connecting rod P is arranged perpendicular to and rigidly connected with one surface of driving element or plane V, while the attaching point of the rod P is spaced about a third of the length of the plane of the forward edge thereof. 7 In this connection it may be stated that the surfaces of the plane are tapered toward their respective ends as indicated, while the rear end is formed of resilient material. The middle portion of the pl'ane is journaled in a cross head slide which operates between the guide Z.

By reason of the foregoing arrangement,

front in the contrary direction and to re- A turn to the initial position 0, whilst permanently upholding the pressure action; 1), which is always approximately perpend1cular to the drlving organthe same time relieves the cross head guides. In this case a prejudicial frontal resistance does not take place, as the longitudinal planes fg and h i are not exceeded with a correct adjustment andlow resilient ter mination similar 'to the fishs tail and to the wing of the bird, which will be apparent from the drawing, in which the driving member successively adopts the position The crank mechanism, the thrust rod of which may be extremely short in this case,

by its alternative movement renders possible the ambi-lateral or 'alsouni-lateral throw ofthe medium substance iipon the driving .member according as 'to whetherthe' system is assumed'to be immersed or suspended in 7 space.

The path areas here, however, are not twice the diameter d, but rather through the angle of inward andoutward swing B, B the entire circular surface is converted into plane sectors, whilst alsothe velocities 11 not only add themselves together through latter or beyond its poles.

the above mentioned 'transvers'e'outward rotations,- but also give a perfectly junifonn movement of the drive and a backward displacement of particles inspace, i. 'e. the rei be used. On the other hand the connecting rod, guided on the'onehan'd in a circular and on the otherhand on a straight line, may only serve as a klnematic guide :for thettr a'ns lation and thevdynamic movem'ent anay be obtalned direct through a straightpiston.

This driving mechanism obtains itsv special development in .the principle ofcrank formation (Figure 2) inthat the funda mental element, W 1s positively connected by guide shoulders F, F, F", .F'T, with it'ur.-

ther similar ori larger similar elements YV,

and hence -at Wf, which participate in the movements, on the straightfline E 6 at any desired distances, guided upon a common slide Z, Z and also "passing; beyond the crank point W.

- According to the purpose in View, all these drives may be arranged horizontally, vertically, or obliquely axially, alsoplaced in pairs opposite each otheror swingin pan allelly, above, beside or behind each other,

in uniform ordifl'erentiated groups. If arranged in pairs the non-symmetry ofthe paths'in theerank drive will be removed and 1 thefrotary momjents willbe compensated for.

The laws thus, found, as illustrated: by comparative mechanism, are represented in the screw,- which coincides with the wave not only p animetrically but also in its spherical development.' i
